Possible Parkinson's disease revealed by a pure head resting tremor.J Neurol Sci. 2009 Apr 15; 279(1-2):121-3.JN
Head tremor is very unusual in Parkinson's disease (PD). Five PD patients presenting a head tremor during the disease evolution have recently been reported. Here we describe a 74 year-old woman with a pure head resting tremor. The tremor was responsive to levodopa and had a 4.7 Hz frequency. A [(123)I]FP-CIT SPECT imaging confirmed a reduction of tracer uptake in the right striatum consistent with PD, that should be confirmed by long-term follow-up.
